About this tool
Convert PNG, JPEG, and WebP images to another format entirely in your browser. Choose the JPEG background and JPEG or WebP quality, compare appearance and file size, and download the result without uploading the image.
PNG can contain transparent pixels, while JPEG cannot. When exporting JPEG, transparent areas are filled with the selected background color. WebP can preserve transparency.
Lower JPEG and WebP quality usually reduces file size, but artifacts may appear around text and thin lines. PNG is lossless and does not use the quality setting.
Images never leave your browser. To keep processing responsive, images longer than 4,096 pixels are reduced before conversion. Check the resulting dimensions and file size before downloading.
FAQ
- Is the image uploaded?
- No. Reading, conversion, previewing, and saving all happen inside your browser.
- What happens to PNG transparency in JPEG?
- JPEG cannot store transparency, so transparent pixels are filled with the background color you select.
- Can WebP be converted to PNG?
- Yes. When the browser can decode the WebP file, it can be saved as PNG with transparency preserved.
- Does conversion reduce image quality?
- PNG is lossless, while JPEG and WebP quality depends on the selected setting. Use the preview to check the result.
